JPG to TIFF Converter
Convert JPGs to TIFF for print, publishing, and archiving — uncompressed RGB, with the print resolution written into the file's resolution tags so it arrives at the right physical size. Useful when a printer, a journal, or a stock library will only accept TIFF. The encoder runs in this page; nothing is uploaded.

How to convert JPG to TIFF
- Drop the JPGs in.
- Set the DPI your printer or publisher asked for — 300 is the usual answer.
- Click Convert to TIFF, then download individually or as a zip.
Check your pixels before you send
Physical print size is pixels ÷ DPI. At 300 DPI, a 1200×1800 px photo prints at 4 × 6 inches, and no amount of re-tagging changes that: tagging a small image at 300 DPI just makes it print small. Work out what you need from the finished size — a full A4 page at 300 DPI wants about 2480×3508 px — and check the source is big enough. The quality checker reports the exact dimensions and megapixels of any JPEG, along with an estimate of the quality it was saved at.
CMYK, and what this does not do
These files are RGB. Commercial print is CMYK, and the conversion between them is a colour-managed step that depends on the press, the paper, and the ICC profile in use — a browser canvas is the wrong place for it, so this tool does not pretend to. Hand the printer an RGB TIFF and let their prepress convert it, or do the conversion yourself in software that can honour a profile. Anything advertising in-browser CMYK conversion is guessing.
FAQ
Why do print shops and publishers ask for TIFF?
Because it is lossless, it carries an explicit resolution, and it has been the interchange format of prepress for thirty years. A JPEG can silently lose quality every time someone opens and re-saves it in a layout program; a TIFF cannot. Journals, stock libraries, and commercial printers ask for it for exactly that reason.
Does the DPI setting change the image?
It changes how large the image prints, not how many pixels it has. The value is written into the TIFF's XResolution and YResolution tags, so a 3000 px-wide file tagged at 300 DPI lands as a 10-inch print. Setting a DPI does not add detail — if you need more pixels, you need a bigger source image.
Will the TIFF be better quality than the JPG?
No, and no converter can make that true. The JPEG artefacts already in the source are copied exactly into the TIFF. What you gain is that nothing further degrades: TIFF is the right format to hand to a printer or to edit repeatedly, and it is the wrong thing to expect quality back from.
Is the output compressed?
No — this writes uncompressed RGB strips, the variant every TIFF reader can open. Expect roughly width × height × 3 bytes. LZW and Deflate compression are optional in the TIFF spec and not every prepress workflow accepts them, so uncompressed is the safe default here.
Is anything uploaded?
No. The TIFF header, its image file directory, and the pixel strips are assembled in JavaScript inside this page. No library, no server, no upload.
